Anhydrobiotic engineering of gram-negative bacteria

Anhydrobiotic engineering aims to improve desiccation tolerance in living o rganisms by adopting the strategies of anhydrobiosis. This was achieved for Escherichia coli and Pseudomonas putida by osmotic induction of intracellu lar trehalose synthesis and by drying from trehalose solutions, resulting i n long-term viability in the dried state.
